ABSTRACT:
A unique method/system for simultaneously creating and transferring a contrasting pattern of intelligence on and from a composite ablation-transfer imaging medium to a receptor element in contiguous registration therewith is improvedly radiation sensitive and versatile, is kinetically rapid and not dependent on a sensitized ablative topcoat, and is well adopted for such applications as, e.g., color proofing and printing, the security coding of various documents and the production of masks for the graphic arts and printed circuit industries; the composite ablation-transfer imaging medium, per se, comprises a support substrate (i), at least one intermediate "dynamic release layer" (ii) essentially coextensive therewith and an imaging radiation-ablative carrier topcoat (iii) also essentially coextensive therewith, said imaging radiation-ablative carrier topcoat (iii) including an imaging amount of a contrast imaging material contained therein, and said at least one dynamic release layer (ii) absorbing such imaging radiation at a rate sufficient to effect the imagewise ablation mass transfer of at least said carrier topcoat (iii).
